88 DIADELPHIA. OCTANDRIA. 



cumbent, apetalous. P.r7ibeUa. WiWd. Hab. In the FT ^ 

 forests of Lake jNIicliigan. Obs. Perennial, and subde- 

 cumbent; flowers reddish. Allied to P. Seiiega. Mr. 

 Pursh's plant appears to differ considerably fi'om the ono. 

 here described, but I am persuaded it is the same, from^ 

 a good specimen which I have seen in the possession of 

 ?'■ Collins, Esq. agreeing with the Michigan plant. 



9. lutea. Stem branching, lower leaves spathulate, upper 

 lanceolate; spike subcapitate, obtuse; wrings of the calix el- 

 liptic, acute, bractes shorter than the flowers. Hab. Kew 

 Jersey to Florida. 10. riridescens. Stem simple or none; 

 radical Ieave& spathulate, often retuse, cauline ovate; 

 spike ovate; wings of the cahx acuminate; bractes nearly 

 as long as the sessile flowers. Hab- In the Pine forests 

 ©f Carolina and Georgia. Obs. Autumnal and winter 

 spikes squarrose and stemless, sessile amidst the radical 

 leaves; ffowers always green with a tinge of yellow. It 

 appears to be very nearly allied to tbe preceding, but 

 what resemblance it bears to P. incnniaia is more than I 

 can imagine,^ and Mr. Pursh*s giving it a habitat in Penn- 

 sylvania almost proves that he bad never seen our plant. 



11. *" purpurea. (P. jyong'J^V/ea, Michaux, Pursh.) An- 

 nual: stem fastigiately branched; leaves alternate, ob- 

 long-linear; flowers beardless, imbricated in obtuse cylin- 

 dric spikes; rnchis squanose; wings of the caKx cordate- 

 ovate, erect, twice as long as the capsule. Hab. Commou 

 throughout North Amerca. Flowers rosaceous. 



12. sangiiinea. L. Annual: stem fastigiately branched; 

 leaves alternate, narrow-linear; flowers beardless, dispos- 

 ed in long and crowt'cd spikes; rachis squarrose; calicine 

 wings obovate, the length of the capsule. Hab. In the 

 low Pine barrens of New Jersey. Flowering in July and 

 August. Allied proximately to P. purpurea, but very 

 distinct; a much smaller plant, with short and narrow 

 leaves; spikes acute, growing out 2 or 3 inches long, 

 loose compared with the preceding; flowers small and 

 sanguineous, or dark red intermixed with green from the 

 imperfectly concealed capsules; the proper corolla yellow- 

 ish; rachis much more squarrose than in the preceding. 

 I believe this to be the P. sanguinea of Linnaeus, though 

 now the preceding, which is much more common, passes 

 for it. This species also accords very well with Plukenet, 

 Mant. 153. t. 438. f 5. 



13. rerticillata. Annual: leaves verticillate, linear and 

 remote; flowers cristate, greenish, calicine wmgs round- 

 ish, nearly veinless, and shorter than the fruit to which 

 Ihey are appressed; spikes pedunculatCj subacute: brae-
